First steps in making a unified program

Created a simple 3 button window.
When the third button is pressed, it launches the level editor.
Things to be done:
Launch the actual game
Move the main character
Move other characters
integrating game and editor into one program

so far there is a main window in which you choose either New game,
continue, or level editor. Right now clicking New game and level editor
"work". But continue doesnt. Also the main window needs to look better.
basic MJ movement
changed mj to point to Node to be able to access the x, y positions
